Abstract

The utility model discloses a waterproof LED streetlamp, which includes an upper cover provided with radiating fin, a front cover matched with and installed on the lower side of the upper cover, and a transparent shield. An LED lamp body is sealed and mounted by the upper cover, the front cover and the transparent shield together; a circle of raised strip is arranged on the outer side of the front cover and around the periphery of the transparent cover; and the outer end edge of the raised strip is a bevel or sharp-angled structure. After the water proof LED streetlamp is adopted, the external rainwater can gradually get together to the lower edge of the outer side of the raised strip and drip onto the ground, so that the rainwater or water vapor can be effectively prevented from leaking into the space for accommodating the LED lamp body, and the waterproof performance and the service life of the waterproof lamp can be remarkably improved.

Description

LED street lamp that can waterproof

Technical field

The utility model relates to illuminator, particularly a kind of street lamp of making illuminator of LED.

Background technology

Street lamp is the important component part of city illumination, adopts the conventional road lamp of high-pressure mercury lamp as light source, is replaced by the LED street lamp of more efficient, safety, energy-saving and environmental protection gradually.

Existing LED street lamp in use, the factor that influences its life-span or reliability mainly comprises two aspects: the one, heat dispersion, the one, water resistance.If the water resistance of LED lamp is bad, in a single day steam or rainwater enter in the LED street lamp body, will speed up the wearing out, damage even short circuit phenomenon occurs of drive circuit of LED street lamp, cause the dead lamp of LED lamp pearl, directly influence the service life of LED street lamp.Therefore, existing LED street lamp generally is the shell that is made of jointly the translucent cover that materials such as loam cake, protecgulum, glass are made when overall package, LED lamp pearl is sealed, as shown in Figure 1, in case the infiltration of steam or rainwater; Be further to improve water resistance, generally also need use waterproof material in the junction of translucent cover with loam cake, protecgulum, seal as silica gel, the sealant tape (bar) of an annular of formation is with reference to Fig. 2 or Fig. 3.

The waterproof construction of above-mentioned existing LED street lamp has obvious defects, main cause is: in the actual use, the protecgulum of street lamp and translucent cover are downward, directly in the face of the road surface, because the surfacing of protecgulum and translucent cover, external steam such as rainwater be generally along direction shown in Fig. 3 arrow, water clock, discharging downwards, junction at translucent cover and loam cake, protecgulum still has the part rainwater to permeate in lamp body because of capillarity; Sealant tape no doubt can stop this phenomenon, but after long-term the use, sealant tape also can wear out at self, is difficult to effectively stop the infiltration of steam, causes street lamp integral body after long-term the use, and water resistance obviously reduces, and then influences the service life of LED street lamp.

Summary of the invention

The utility model aim to provide can waterproof the LED street lamp, solving in the prior art, the LED street lamp is difficult to the deficiency that effectively stops rainwater or steam to permeate in lamp body.

The scheme of technical solution problem of the present utility model is: a kind of LED street lamp that can waterproof, comprise the loam cake that has fin, protecgulum and the translucent cover that cooperation is installed in described loam cake downside, described loam cake, protecgulum and translucent cover are installed LED lamp body sealing jointly, it is characterized in that: in the described protecgulum outside, be provided with a circle raised line around the periphery of described translucent cover.

Further, the outer end edges of described raised line is the structure of knuckle or wedge angle.

After adopting the utility model, because in the protecgulum outside, be provided with a circle raised line around the periphery of translucent cover, when rainwater from the outside following current of loam cake during to the protecgulum downside, will focus on gradually the place, lower edge, the outside of raised line, and drop onto ground, and can be not oppositely from the inboard of raised line, therefore, even if the utility model uses for a long time, still can effectively stop rainwater or steam in the space of ccontaining LED lamp body, to permeate, thereby can obviously improve water resistance of the present utility model and service life.

Below with reference to drawings and Examples, the utility model is further described.

Description of drawings

Fig. 1 is existing LED street lamp general structure schematic diagram.

Fig. 2 is existing LED street lamp cross-sectional view.

Fig. 3 is the partial enlarged drawing of LED street lamp waterproof construction shown in Figure 2.

Fig. 4 is a LED street lamp cross-sectional view described in the utility model.

Fig. 5 is the partial enlarged drawing of LED street lamp waterproof construction shown in Figure 4.

Fig. 6 is a LED street lamp general structure schematic diagram described in the utility model.

Among the figure: 1, LED lamp body, 2, loam cake, 21 fin, 3, protecgulum, 4, translucent cover, 31, raised line, 5, sealing joint strip.

The specific embodiment

As Fig. 3, Fig. 4 and shown in Figure 5, a kind of LED street lamp that can waterproof, comprise the loam cake 2 that has fin 21, cooperate the protecgulum 3 that is installed in described loam cake 2 downsides, and the translucent cover of making by glass or other transparent material 4, described loam cake 2, protecgulum 3 and translucent cover 4 are installed 1 sealing of LED lamp body jointly, like this when guaranteeing that LED lamp body 1 is positioned at road surface below the street lamp by the translucent cover irradiation, can prevent that still extraneous rainwater or steam from entering in the lamp body, infringement to the drive circuit of LED, usually at loam cake 2, protecgulum 3 and translucent cover 4 in conjunction with part, still can use marine glue to make a circle sealing joint strip 5.

In order further to improve water resistance of the present utility model, the utility model is especially in described protecgulum 3 outsides, be provided with a circle raised line 31 around the periphery of described translucent cover 4, descend along the trickling of loam cake outer rim at rainwater like this, to drip naturally because of himself weight in the outside of raised line 31 (or downside), upwards being penetrated into translucent cover again locates with the slit that combines of loam cake, protecgulum, that is the rainwater direction shown in Fig. 5 arrow drippage the most at last; As long as the height of raised line 31 is enough, rainwater or steam will thoroughly be prevented from because of the seepage of capillarity, can upwards not penetrate in the LED road lamp body again, can not cause damage to internal circuit; In order to prevent above-mentioned rainwater or steam seepage better because of capillarity, the outer end edges of aforementioned raised line 31 can for shown in Figure 5 be the structure of knuckle or wedge angle.

Adopt the special raised line that is provided with, its principle is similar to common being seen eaves structure, though simple, water resistance and effect can be because of the prolongation of LED street lamp service time variation, obviously improve water resistance of the present utility model and service life, very reliable.
